The system of air EXTRACTION with “Settling Chamber” has to assure continuous air exchanges, its main aim is to transfer externally the heat dissipated by the equipment in the radio base stations and Data Processing Centre.
This happens thanks to the combined operation of the air extraction and the settling chamber (inlet air).
The settling chamber can be installed externally or internally, in according with the typology of the installed air conditioners and with the space available inside the local.
1 – assembly ventilation system (fan, plate grid);
2 – external plenum with overpressure damper;
3 – settling chamber (internal or external);
4 – electrical panel “Command and Control” consists of general disconnecting switch breaker, PLC PB13, maximum temperature thermostat.
The system is designed to be managed by its own PLC PB13 to manage the operation cycle and detect the possible causes of alarm conditioning system.
Adjusting the temperature “ON-OFF” or “proportional” (0-10V). By adopting the regulation “proportional”, they avoid thermal shock conditions when the outside temperature is very low.
This system can also be identified as an emergency system to cool the room as it is provided an electromechanical controller (thermostat) that allows to feed the fan in an independently and separately when the detected temperature exceeds the predetermined values and simultaneously indicates the condition of emergency operation.
